so you'd be at the top of 3rd, drop it down to 2nd and dump the clutch. you'll either break your gearbox or diff (or engine) or the rear wheels will lock up until you've slowed down enough for them to spin again at the appropriate rpm for the gear you're in. try it with some shitty tires in the wet, too many compression lockups WILL kill your motor, my mate pete put a rod through the side of his old 4k after about, oh, 2 years of it :thumbsup:
